Thank you for sharing this! Fascinating from a programming perspective to get a look behind the curtain.
You're welcome! I want to document more of my work so that people have regular news updates on what I'm up to.
Doing the harmonic analysis of the Blackmer VCA made me aware of just how slow circuit simulators are for getting high resolution results. I can take an LTSpice created netlist, generate code from this to make a plugin (VCV Rack module), and have this compiled and loaded up with a realtime spectrum analyser as I adjust parameters all in around 40 seconds. It took LTSpice 90 seconds to generate a single static spectrum. I can make changes to any values instantly, LTSpice takes another 90 seconds each time I change any parameter values. LTSpice takes around x1000 more cpu to simulate the circuit compared to the generated code.
